6.4.8 SPECIAL HANDLING PROCEDURES <br /> The following sections describe special handling procedures for land treatment <br /> units, sludge treatment and disposal and disposal methods for asbestos, ash and <br /> treated wood waste. <br /> 6.4.8.1 LAND TREATMENT UNITS <br /> Although most contaminated soils accepted at the existing Forward Landfill are <br /> disposed directly into Class II WMUs or are used as daily cover, Forward may <br /> occasionally choose to temporarily stockpile or treat certain contaminated soils. <br /> Soils that are temporarily stockpiled are typically those that have been received at <br /> the site without the required analytical testing documentation. The soils are <br /> stockpiled until the generator provides the necessary documentation. Once the <br /> documentation is received and depending on the test results, the soils are either <br /> disposed in an appropriate WMU or removed from the site by the generator. <br /> In order for Forward to process a request for treatment or disposal of <br /> contaminated soil, the potential disposer/generator must complete a waste <br /> characterization form and a contaminated soil description form (signed by a <br /> California Registered Geologist or California Professional Engineer), and submit <br /> copies of all state-certified laboratory results for the contaminated soils. <br /> In the past, Forward has implemented programs for treating both gasoline and <br /> nonvolatile petroleum hydrocarbon contaminated soil. A brief operations <br /> summary for treatment of both of these contaminated soil types follows. <br /> Treatment of Nonvolatile Petroleum Hydrocarbon Contaminated Soil <br /> The "Operation and Maintenance Manual, Soil Treatment System, Forward, Inc., <br /> Landfill Unit WMU G, Stockton, California" (Harding Lawson Associates, April <br /> 1991) describes the treatment system for nonvolatile petroleum hydrocarbon <br /> contaminated soils. The specifications and reporting requirements of the <br /> treatment system are specified in the WDRs, Order No. 97-141 and in the <br /> October 31, 1990, letter from SJCPHS to Forward. <br /> The contaminated soil treatment system consists of an area where appropriate <br /> fertilizers are added to the contaminated soil and the soil is mechanically aerated <br /> Forward Landfill JTD 6-14 <br /> ):\Allied\Forward\JTD Amendment\january2006)TD Amendment\)TD Sec 6 012506 Accept.doc: BRYAN A.STIRRAT&ASB®CIATES <br /> 5/22/02;Rev.1:7/2002:Rev.2:4/2003;Rev 3:6/2003;Amendment No.1:1/26/2006 <br />
